How To Fix CNV_20375_CHECK048 - Mapping onto account &1 detected

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20375_CHECK - Message Class for 20375 Checks

• Message number: 048

• Message text: Mapping onto account &1 detected

What causes this issue?

A target value in the mapping has the same value as an account.
There is a 1:1 relation between accounts and primary cost elements,which
is realized by providing the same name for the corresponding objects. If
a cost element has the same name as an account, it is considered as a
primary cost element. Therefore a rename or merge to a name that is used
by an account is not permitted without a chart of account conversion.
You cannot run the transformation solution because certain prerequisites
have not been met. Please change your mapping accordingly.
